Abstract: 905,782. Engine turning gear. GRIMMINGER & SCHIP G.m.b.H., [trading as HIRTH MOTOREN KOMM.-GES.] Dec. 14, 1960 [June 3, 1960], No. 43045/60. Class 7(5) In a starting device for an internal-combustion engine a torsionally elastic coil spring 21 serving as a coupling member and embracing a part 11 to be driven is adapted to be turned at one end 23 and thereby twisted during the starting operation in such a manner that its coil diameter is reduced and it grips firmly around and turns the part 11 and on completion of the starting operation automatically frees the part, the other end of the spring being engaged with a fixed part 12 in such a manner that the other end can when the device is operated slide on the fixed part with a lag in relation to the one end as soon as the spring has firmly gripped and turned the part to be driven. The other end of the spring may have a polygonal shape in the region where it bears against the fixed part. The turns of the spring at the ends of the latter are advantageously wound close to one another.

Abstract: 1,215,277. Supply circuits for discharge lamps. VARIAIST ASSOCIATES. 8 Sept., 1969 [10 Sept, 1968], No. 44349/69. Heading H2H. A circuit for starting and operating a gas discharge lamp includes a capacitor which is discharged through the primary winding of a transformer. As shown, a high voltage battery 3 is connected to a xenon lamp L by way of a switching circuit 12 which includes an SCR 16, a Zener diode 15, and a four-layer switching diode 17. Initially, two capacitors 8, 9 are charged from the battery 3, the diode 15 breaks down, and another capacitor 13 charges until the diode 17 breaks down, whereupon the SCR 16 is triggered and the capacitor 9 discharges through the primary winding 1 of a transformer T. The induced voltage causes the lamp L to strike, and the capacitor 8 now discharges through the lamp and the secondary winding 2. A resistor 10 prevents the capacitor 8 from discharging through the switching circuit 12. The current in the secondary winding 2 increases rapidly, assisted by the presence of a diode 11 shorting the primary circuit, until the transformer T saturates, maintaining the lamp L ionized. When the voltage across the capacitor 8 falls below that across a further capacitor 7, a diode 5 becomes conductive allowing the lamp to be continuously supplied from a low voltage battery 6. The lamp can be operated in a pulse mode if the diode 5, battery 6 and capacitor 7 are omitted.

Abstract: 876,108. Stripping cables. AMP Inc. Dec. 31, 1959 [Dec. 31, 1958 (2)], No. 44383/59. Class 36. A method of stripping the end of a sheath 8 from a conductor 15 comprises gripping the sheath so as to grip the conductor within it at a point back from the end, pushing the sheath axially back towards the gripped point to form it into a bulge 17 and cutting around the periphery of the bulge in the longitudinal direction of the conductor to sever it. The conductor may be held, either by a clamp or by hand, within a support 2 having a passageway 4 terminating in a knife edge 8 which thus surrounds the sheath. A device 10 for pushing the sheath back has a bore 16 which will receive the bared conductor but not the sheath, the latter terminating against the shoulder 18 of a recessed part of the bore. Movement of the parts 10 towards the support 2 causes the bulge 17 to form, this being severed by the knife edge 8. The method may be used for stripping the metal braid from an insulated conductor, and the cutting device may be a hard metal sleeve carried on the support and telescoping into a similar sleeve on the pushing device. Cutting may be facilitated by rotating the cutter or, where appropriate, by heating it. A plierlike tool (Figs. 5 and 6, not shown), and also a pneumatically-operated apparatus for stripping braiding (Figs. 7-10, not shown), is described.
